Paper Number: OTC-26169-MS
... A study is presented of the potential capacity of pipeline vibration dampers (PVDs) to mitigate vortex induced vibration (VIV) for subsea pipeline spans. The study also makes evaluations for VIV fatigue damage reductions that could be accomplished by PVDs for the spans. While it is recognized...
